appearance being flown very few purists will insist scale prop must also fly plane have seen successful examples extent being adjustable air frequently asked questions static displays whether model would fly static prop answer depends upon number factors Several scale props carved left-hand early planes modeled after plane auto engine rotate opposite direction Obviously could fly model other scale props properly balanced would fly model However best performance modern glow plug engines scale prop should replaced matches engine perfor mance obvious real reason scale prop cant used absence prop nut isnt fastened shaft securely center hole drilled slightly undersize thread onto engine shaft Carving prop difficult made proper material carves easily prefer basswood two reasons has little grain means knife goes directed rather following strong grain some materials Secondly easily available Most hobby shops stock Midwest Northeastern basswood planks can laminated Continued page 112

since flying prop shape cut saw will determine pitch knife used bring shape its final form very little sanding required bring blades down equal thickness fingertips will tell much eyesight Time spent up point will less hour carving sanding Have no regrets must discarded because doesnt look right purchased flying propeller can used pattern blade thickness airfoil front view will likely correct nor will portion blade near hub Model flying props usually have sharp unfinished edges near hub seen full-size hub thickness reduced comparison scale prop will have hub thickness nearly double typical store-bought prop three-blade controllable-pitch prop made individual carved blades cemented hub easier carve two-blade prop cutting through center afterward since blade can held carving other hub
